> Hey Alistair -

Maybe I can drop it off to you next week and you can give it a good go over
as I'll be on my way to Cowichan Lake!  Anyway - checking to see if the GW
supplier here in town has another aluminum tank to swap as a warranty.  If
nothing is available I'll be going back to plastic for a little
while...kicking myself that I didn't keep the plastic tank I had...or where
the heck I stored it.

I find it interesting that after 3.5 months now a leak is appearing - it is
very minor and dripping only under pressure.  So how would a seam weld
alter over time -  possibly a slight flaw and through the heat of the tank
expanding and contracting over the last number of trips a deep enough crack
has formed?  If so, you would think testing should involve more than
pressure testing.  X Raying the seams perhaps? - That would increase the
cost at the end of the day....likely just a big fluke.
